var/system/journal logs flooded with i2c_hid i2c_hid_get_input: incomplete report (14/65535)

You can try to follow the solution of Pablo Abrudsky in here. It worked for me. You'll need to access to /etc/default/grub and change GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_osi=" and then run:

$ sudo update-grub

And finally, vacuum the journal. Good luck!!!
